To all whom it may concern:

Be it known that I, ALBERT B. DIss, a citizen of the United States,residing at New York,

borough of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Casters, of which the following is a specification.

My invention relates to casters especially adapted to bedsteads having tubular legs,usually with an ornamental surface of brass. These tubes extend down closely to the place where the caster is connected, and the caster passes up into the tubular leg and is frictionally held therein, the disk of the caster coming against the end of the tubular leg.

In carrying out my invention I provide a spring frame connected to and spanning the vertical pintle and acting frictionally against the inner surface of the tubular leg and wings that are radial to the pintle, the vertical edges of which wings bear on the inner surface of the tubular leg to maintain the pintle of the casters vertically in place. I prefer to make the spring-frame and wings integral and to stamp the same up out of sheet metal, with a round hole in the center and with elongated holes at the respective ends, and the ends of the frame are bent at right angles to the adjacent part, and the portions carrying the wings are bent parallel to one another and the wing portions at obtuse angles to said parallel faces, with the central part of the frame also at right angles to the parallelportions. This frame fits over the pintle and is held thereto by upsetting the free end of the pintle, the pintle passing through the round hole at the upper part and through the elongated holes at the lower part, the lower part of the frame having a movement at said elongated holes, so that the frame springs as the same is inserted into the tubular leg.

In the drawings, Figure 1 is a vertical section representing my improvement. Fig. 2 is a sectional plan at a: 00 of Fig. 1. Fig. 3 is a view of the frame out flat, as the same would appear when out out of sheet metal; and Fig. 4 is a vertical section representing a modification.

a. represents the caster-wheel, the axis of which is connected to the jaws b, said jaws being preferably made integral with the jaw top b. The pintle c is connected to and rises from the jaw top and in use occupies a vertical position. The disk d is of usual character and surrounds the pintle c and comes against the end of the tubular leg 6, so as to support the article, of which said tubular leg is a part. The spring-frame f, as shown in Fig. 3, comprises a narrow central portion, with a round hole 2, adjacent wide portions at each side thereof, and end portions which contain the elongated holes 3. Figs. 1 and 2 show the manner of bending up this frame, the end portions having the elongated holes being bent at right angles to the adjacent portions, the central portion at the edges of the adjacent portions being bent over, so that the central portion comes at right angles to the adjacent portions, and said adjacent portions form parallel faces, the wings f being bent outward at the dotted lines 4 of Fig. 3, so as to come at obtuse angles to the parallel faces of the frame and, as shown in Fig. 2, to stand radial to the pintle.

In stamping up the frame one end, with its elongated hole, comes above the other end, so that the said holes are one above the other, and the frame in its normal condition is slightly wider across the base than the top, so that when the pintle is inserted through the holes 3 and 2 the outer edges of the holes 3 bear against the opposite sides of the pintle. The upper end of the pintle is upset to form the projections 5, so as to keep the frame thereon.

NVhen the caster is connected to the tubular leg and the spring-frame is forced therein, the same yields as the edges of the wings come in contact with the inner surface of the tubular leg, and in this yielding position the inner edges of the elongated holes come against the tubular pintle, so that together they form a practically-round opening for the pintle, the same as the round opening 2 near the upper end of the pintle. The spring action of this frame keeps the edges of the wings in contact with the inner surface of the tubular leg, so that the pintle is steadied and maintained central, and is held frictionally, so that the caster does not drop away from the tubular leg. The weight of the-tubular leg and the article of which it forms a part is received upon the disk 01 and is thereby trans surfaces of the tubular leg to hold the caster in place.

I claim as my invention- 1. The combination with the caster-wheel, jaws and pintle and a disk surrounding the pintle and upon which the tubular leg rests, of a spring-frame spanning the pintle Within the tubular leg and adjacent to its respective ends and acting outwardly against the inner surface of the tubular leg to maintain the same centrally in position and the caster frictionally to the tubular leg, said spring-frame having openings at the upper and lower portions for the pintle and means for securing the spring-frame to the pintle substantially as set forth.

2. The combination with the caster-wheel, jaws and pintle, and the plate or disk surrounding the pintle and on which the tubular leg rests, of a spring-frame spanning the pintle and having two portions parallel with each other and with the said pintle and integral wings with said parallel portions and ends having elongated holes and a center having a round hole through which the pintle passes, substantially as set forth.

3. The combination with thecaster-wheel, the jaws and pintle and a plate or disk surrounding the pintle and upon which the tubular. leg rests, of a spring-frame f spanning the pintle and provided with four wings f integral with the parallel portions of the frame and formed at obtuse angles thereto and radial to the pintle, the center of the frame having a round hole for the pintle and the respective ends of the frame having elongated holes for the pintle and lapping over one another, the vertical edges of the Wings taking a bearing upon the inner surface of the tubular leg and the lower portion of said spring frame yielding as the same is inserted into the tubular leg to hold the caster central and frictionally in place,substantially as set forth.

4:. The combination with the caster-wheel, jaws and pintle and a disk surrounding the pintle and upon which the tubular leg rests, of a centering frame stamped out of sheet metal and comprising a narrow central portion and narrow ends with holes, and wide intermediate adjacent portions, and bent up to shape with the wide portions parallel and the .end portions lapping and parallel with the central portion, the pintle passing through the several holes and means for securing the frame to the pintle, substantially as set forth.

5. The combination with the caster-wheel, jaws and pintle, and a disk surrounding the pintle and upon which the tubular leg rests,

of a centering-frame stamped out of sheet metal and comprising a narrow central portion and narrow ends with holes and wide intermediate adjacent portions and bent up to shape with the wide portions parallel and the end portions lapping and parallel with the central portion, the pintle passing through the several holes and means forsecuring the frame to the pintle, and means for holding the caster frictionally in place in the tubular leg, substantially as set forth.
